diode - A two terminal device that conducts in only one direction.
gunn diode - A semiconductor diode that utilizes the Gunn effect to produce microwave frequency oscillation or to amplify a microwave frequency signal.
junction diode - diode. A semiconductor diode in which the rectifying characteristics occur at a junction between the n-type and p-type semiconductor materials.
light-emitting diode - A semiconductor diode that converts electric energy into electromagnetic radiation at a visible and near infrared frequencies when its pn junction is forward biased.
photodiode - A semiconductor diode that changes its electrical characteristics in response to illumination.

Types
Types of Diodes Small Signal Diode - Low voltage/current diodes. Power Rectifier - High voltage/current diode. Bridge rectifiers are are four diodes pre-installed into one component, useful for

Diodes
Diodes Diodes are one of the most common semiconductor devices. As we know from the last page, both N and P type silicon conduct electricity. The conductivity (or resistance) of both is by how doped

Quick Voltage Dropper
Quick Voltage Dropper If you fliped through our section on semiconductors you might have noticed that silicon diodes need at least 0.6 volts to work and reduce the voltage by 0.6 volts. So we can tak

Drawing Circuits
Drawing Circuits When designing circuits it is not practical to draw physical likenesses of the components you wish to use. In place of each component a symbol is use to represent it. For example:

Bipolar Transistors
Bipolar Transistors One of the two types of transistors are bipolar transistors. From Diodes we learnt about PN junctions. Now with bipolar transistors we add another layer to make it PNP or NPN depe
